i makes formula on the column in oracle forms
such as
column it's name
column1 and this column return value from another column column2
and used the
calculation mode = formula
formula = (:column1 + :column2)
the formula will be
(:column1 + :column2)
and this formula will appear in column3
how can show column3 in oracle report ?

Almost the same way you do that in Forms - you'd create a "formula column" (you'll see it on the toolbar). Its code would be similar to Forms:
begin
  return (:column1 + :column2);
end;

"Steps" might depend on what you did so far so - provide some more information. What is a formula column supposed to do? What are its inputs - are they columns returned by report's query? Other formula columns? Parameters you passed to a report? Something different?

Did you read Reports Help on formula columns? If not, perhaps you should.

P.S. What does "nothing happened" mean? If there's no result, perhaps one of input values is NULL so, if you didn't handle that situation properly (such as using the NVL function), return value *might* be NULL as well.
